Comment

David Cameron is today addressing issues of constitutional reform as more polls suggest that even though the Tories might get the biggest share of the vote, Labour might get the most seats under the First-Past-the-Post system. The Conservative Party have had a long-standing opposition to any form of proportional representation. In a hung parliament however, the Liberal Democrats may demand it as a condition of support for another party.
